CHECK PROTECTOR. 4

Application filed April 28,

' tions of a negotiable instrument, for example. where there is likelyto be unlawful alterations in the writing, that no further writing onsuch portions is possible after the instrument has been operated Thisresult is obtained without rendering the original writing illegible.

An object of the invent-ion is to provide a paper mutilating devicewhich will be cheap to constructan'd there-byfill the need for aninexpensive protector.

Another object of the invention is to so construct the protector that itmay be conveniently carried a key ring.

Other objects of this invention will in part be obvious and in parthereinafter out.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of'parts which will beexemplified in the construction hereinafter described and of which thescope of applicapointed tion will be indicated in the following claims.

In the accompanying drawing, in which is shown oneof the variouspossible illustrative embodiments of this invention,

Fig. 1 is a perspective view of a device embodying the invention showingits approximate size.

Fig. 2 is an enlarged plan view thereof. Fig. 3 is a vertical sectionalView taken along the center line of Fig. 2.

ig. 4 is a fragmentary perspective view of a modified form of theimproved 'devica- Fig. 5 is a view of a. sample check showing how thedevice renders alteration of the same impossible after it is prepared bythe maker.

Referring to the drawing, 10 denotes a. check protecting deviceembodying the invention which is seen to comprise plates 11 made of anysuitable resilient material, each plate being preferably stamped in oneoperation from sheet material'to have depressed edge portions 12; a slot11*; a lug 13; and an opening 13; projections 14; and the guiding endportions 15. These plates 11 are all of i'dentical shape and size andany two of them may be assembled in a cooperating relation with theportions 12 coinciding and the lug 18 en tered into the openings 13.Rollers or die upon by this device.

' projecting lugs 20 which register on the person, for example, on I tobe carried in the 1926. Serial Ila 105,060.

members, one male 16 and the other female 1?,are mounted in the plates11 by being journaled between the projections 14. The surface oftherollers may be formed with any convenient serrations, channels, pyramidsor corrugations which properly mesh for destroying the smooth surface ofa paper or a check passed between them. Devices such as these are wellknown in the art and forthe purposes of this invention need plainedfurtherspring plates is placed thesli'de 19 having the with slots 11 andthereby serves the double func'tion of retaining the slide againstlateral movement and also of enabling the slide to be properlyposition-ed with respect to the dies 16, .17 by the hand of the user ofthe device. '1 It is highly desirable to provide the protector with asharp instrument such as a pen knife, for example, and such instrumentmust be con'ipletely shielded when not in use,'for the reason that thepresent device is designed pocket. To this end, the rear portion 19 ofthe slide 19is formed in any well understood manner, preferably as shownto function as a pen knife, V, o A rivet 21 passing through the plates11 be tween the portions 12 firmly joins the plates togetherand in viewof thev factthat said port ons 12 are offset,-the remaining-oppositelydisposed portions of the plates are normally positioned in spacedrelation. The lateral displacement of the plates 11 is prevented by theengagement of the lugs 13 in the openings 13 as is clearly seen fromFigs. 1 and 2. The die members 16 and 17 are thus normally held apart topermit the insertion betweenthem of a .sheet or sheets of paper to beoperated upon. The material of the plates 11 is of such resiliency thatthe pressure of the hand of the user may readily bringsaid die membersinto cooperative relation to operate upon the sheet of paper in-the wellunderstood manner.

A bail or ring 22 maybe provided preferably being anchored by the rivet21 to enable the device to be attached to a key ring, chain or the like;1

In the modificationshownin Fig. 4, the relation of the parts is the sameas in the preceding figures except that the lugs 13 and openings 13 areeliminated and the flattened collar or band 25 is placed over the plateends having the depressed portion 12, and the rivet 21passedtherethrough. This gives a rigid g .ment.

tained the paper may be withdrawn by restructure and precludes theshifting of the plates laterally.

The operation of the device is as follows: The check is inserted betweenthe guides 15 and the slide is moved so that the edge of the check abutsthe leading edge of the slide 19 when the portion to be mutilated isbetween the rollers. The plates 11 are now pressed together, and theprotector andv paper are moved relatively until the portion tobemutilated has been passed between the rollers. The rear port-ion 19 ofslide-19 is provided with a slot 19 through which the rivet 21. isreceived to. allow 19 and also to cooperate with lugs :20andrestrainingslide 19 from lateral movement. The edge of the slide servesto guide the move- Whenthe desired mutilation is obleasingthe pressureon the plates,

It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved and which is well adaptedto meet the conditions of practical use.

' As various possible embodiments might be made of the above invention,and as various changes mightbe made in the embodiment above set forth,it is to be understood that all 'matter herein set forth or shown in theaccompanying drawings is to be interpreted as illustrative and not in alimiting sense. 1

Having thus described my invention, I claim asnew and desire to secureby Letters Patent 1. A device for mutilating a sheet of paper whichcomprises a pair of rotatable die members yieldably mounted for movementinto and out of cooperative relation, and a gage slidabl'e relative tosaid dies, to guide said joined at one end sliding movement oi slideprojecting lug on both sheet in relation to the dies and to maintainsaid dies normally in slightly spaced relation.

' 2. A device for mutilating a sheet of paper which comprises av pair ofcooperating the justable with respect to said die members and serving tospace said members normally slightly apart, and adapted to guide thesheet in the movement of the sheet in the cevice, and means to move saidslide into position.

' 3. A device for mutilating a sheet of paper which comprises a pair ofspring members and having the free for resilient movement toward eachother, a mutilat-ing'roller mounted on each oi said free ends, saidrollers being retained nor- Y mally out of contact and adapted to bepressed into cooperative relation, and a guide for said sheet of paperprovided by the'inner edge of a tool slidably retained between anadapted to be housed by said spring members.

4. A device for mutilating a sheet of paper which comprises a pair ofresilient members joined together at One end and having the other endsfree, each of said members having a longitudinally disposed slot, a pairof rotatable die members journaled in the free ends of said members, aplate adapted to be pro jected from between said members having a sidesthereof, said lug being slidable in said slots, and a guiding edge onone end of said slide.

5-. A device for serrating paper which comprises a pair of similarslotted members, a retatable die membermounted on each or said slottedmembers, and a gage slidably mounted between the slotted members andguided by the slots therein. I i r In testimony whereof I ai'lx mysignature.
